String parsedValue = DEFAULT_VALUE;
try {
if (myValue != null) {
parsedValue = parse(myValue);
}
} catch (ParseException e) {
log(e);
}

I'm designing a Tokenizer / Parser / AST. I'm wondering if this basic idea of an expression is good and if this way of implementing Simplification is good, or should I use something like the Visitor pattern? Is implementing it in the class itself a good idea?

I am writing a script that will run several versions of the same program in different languages so it should be able to detect if the system can run the file first.
I use the following approach to check if a program is installed.

Suppose I want to find the index of the maximal value of a given sequence. In Matlab, this is:

In Python, I would write (again and again) the following pattern:
best_item = ...
index_of_best = ...
...
for (index, item) in enumerate(items):
...
if item > best_it...

A while ago I started solving Binary Puzzles. Not having done much C++ in my life, although it feels like I have a pretty good understanding of C++ in general, I figured it was time to do some C++!
The rules for a Binary Puzzle are:
